I have experimented with ibus telem, but I haven't been able to to get it to work. I went back to the normal firmware because I was having issues with my EZ ID as a gps, but I tried it again today after resetting everything and then it wouldn't even power on. After further testing, I think that I burnt out another GPS. I did get in some amazing FPV flights with the little EZ pack plane (and I think I set an altitude record too for those planes) and I tried to make it work without a gps, but there is always the ekf3 error whenever I try to arm. I am not sure what else I can change, because I have looked at almost every possible parameter that seems relevant, but I can't find anything. Does anyone know what these parameters could be?
